Serial No. 590,372.

Fig. 13 is a detail view of the cams for feeding the itemized receipt.

The machine disclosed comprises three groups of amount keys 30, approximately only one-half of the keyboard however being shown in Fig. 1. These keys are pivoted on a transverse rod supported in the side frame members of the machine and at their rear ends bear against a key coupler 31 with which they cooperate in the usual manner.

The rear ends of the keys support item indicators 32, and also uprights 35 which are notched to cooperate with rods on rocker members 36 supported on a shaft 37 to move said members proportionate to the number of units represented by the keys depressed.

Totalizer actuators 40 are operated by these rockers, the units actuator being directly secured to its rocker, which is free to rock about the shaft 37. The dimes rocker and actuator are pinned to the shaft 37. The dollars actuator is driven by a pinion 41 fixed to a shaft 42 which is driven by a pinion and segment from the dollars rocker (not shown). This method of connecting the higher order rockers with their actuators is old and well known in the art and is shown in connection with the tens of dollars actuator and rocker in United States patent to Cleal No. 998,602.

The units totalizer actuator cooperates with a pinion 45 secured to a shaft 46 upon which the units type wheel is mounted. The item type wheels are generally designated by the numeral 47 (Fig. 2). The dimes type wheel is set up by means of a segment 48 pinned to the shaft 37 and meshing with a pinion 49 on a tube 50 see also Fig. 3) supporting said type wheel. Pinned to the shaft 42 which controls the dollars totalizer actuator is a pinion 51 in mesh with a segment 52 free on the shaft 37 and in mesh with a pinion 53 on atube 54 to which the dollars type wheel is secured. By means of the mechanism so far described, the item type wheels are adjusted to print the amount represented by the keys depressed.

A cam shaft (Fig. 5) which constitutes the main driving shaft is given one rotation during each item-entering operation of the machine. A pinion 61 secured thereto is driven from a double rack 62 guided on a stud 63. This rack is driven from the key coupler by means of a stud 64 projecting from the key coupler into a slot in the rack and is thrown alternately into mesh with the pinion 61 by a spring 65 and a springpressed pawl 66. A flange 67 on the rack cooperates with a flange 68 on the machine frame to hold the rack and pinion in mesh during up-and-down movement of the rack. The right hand end of the shaft 60 (Fig. 3) carries a cam 70 which cooperates with a spring actuated arm 71 curved through the printer frame '7 3 and provided with a platen 7 2 2) for taking. impressionsfrom the item type wheels. The spring actuating the arm 71 is supported on'one end of an adjusting lever 87 (Figs. 2 and 3) secured to the printer frame 73 by screws one of which extends into a slot in the lever, the other being screwed into the lever and supported in an eccentric 88 mounted in the printer frame.

The issuing receipt strip is fed during item printing operations by mechanism actuated from the key coupler. comprises a key coupler trunnion 75 (Fig. 2) which extends through the printer frame 73. An arm 7 6 (Figs. 2 and 3) is pinned to the trunnion inside of the frame and carries a pin 77 extending through a slot in the frame into an arm 7 8 loosely supported on the trunnion outside of the frame. The aria? 8 is-held on the trunnion by aclip T9 engaging a groove in a hub rigid with said arm, as indicated in Fig. 2. The arm 78 drives a pawl 80 which co-ope'rates with a ratchet 81 rigid with a feed roller 82 secured to a shaft 83. A tension roller 84 holds an issuing receipt strip 85 in feeding engagement with the feed roller 82. The strip 85 is fed from a supply roll 86. Also operated from the arm 78 is ali'nk 'connected to an arm 91 which operates a feed roller 92 for an inking ribbon in a well known manner. The inking ribbon passes between the item type wheels and issuing strip and in cooperative relation with total type wheels later referred to. The totalizer comprises elements (Fig. 4) mounted upon a turn-to-zero shaft 101. Each of these elements comprises a pinion adapted to move into mesh with a totalizer actuator 40. In addition the element comprises a ratchet wheel, and a transfer tooth 102 for cooperation with a transfer pawl supporting arm 103 controlling the position of pawl 104 which is operated by a transfer arm 105 operated from a cam 106 secured to the cam shaft 60. Tripping of the pawls 104 during turn-to-Zero operations is prevented by arms 107 carried by a s iaft operated by an arm 108 1) actuated by a cam 109 secured to the tu-rn-to-zero shaft 1 01.

The totalizer is supported in a frame 110 pivoted at 111 and rocked into engagement with the actuators by a bifurcated arm 112 This mechanism which carries rollers cooperating with a cam 113 secured to the shaft 60.

Each of the totalizer elements is also provided with a gear 114 which meshes with a gear 115 carried on a rod supported in the totalizer frame. During a totalizing operation, which will be set forth later, the cam 113 functions to hold the totalizer frame and gear 115 against bodily movement about the pivot 111.

Total printing and indicating mechanism.

Total type wheels (Fig. 2) are connected by a tube line 121 (Fig. 3) with pinions 122 in mesh with segment gears 123 loosely supported on a shaft 124. Integral with segment gears 123 are segmentgears 125 in mesh with gears 126 connected by a tube line 127 with gears 128, said tube line being Supported on a rod 129 carried by bracket 130 and the printer frame 7 3. Gears 133 in mesh with gears 128 (Figs. 1 and are mounted on a rod 134 supported in an arm 135 pivoted on the rod 129 and in an armof a lever 136 (Fig; 3) also pivoted on said rod. The movements of said lever are controlled by a pitman 137 and a box cam 138 (Fig. to engage the gears 133 with the gears 115 at the proper time during a total-taking operation. The pitman is bifurcated to straddle a shaft 164 to which the cam is secured and carries a roller 139 cooperating with said cam.

T he segment gears 125 also control the position of the indicators through segment-- gears 140 rigidly connected thereto. The segment-gears 140 mesh with segment-gears 141 in mesh with segment-gears 142 integral with. segment-gears 143 in mesh with pinions 144 on a shaft 145. The pinion 144 of the units order is secured to the shaft 145 upon which left and right hand total indicators 146 (see also Fig. 1) are pinned. The pinions of the other orders are rigid with gears 147 rotatably supported on the shaft 145 and in mesh with gears 150 secured on the shafts 151 to which pinions 152 (see also Fig. 4) are secured which mesh with gears 153 on the left and right total indicators.

The segment-gears 142 and 143 (Fig. 3) are alined by alining means with which cooperate spring-pressed alining pawls 161 actuated by a pitman 162 controlled by a cam 163 secured to a shaft 164 (see also Fig. 12). The shaft 164 (Fig. receives its rotation from a gear 165 secured thereto and in mesh with a gear 166 secured to a shaft 167 which caries a gear 168 (Fig. 2) in mesh with a gear 169 driven from any suitable operating means.

The total type wheels and total indicators are returned to zero at the beginning of a total-taking operation by a yoke .170 (Fig. 3) provided with an arm 171 operated by a pitman 172 whose movements are controlled by a cam arm 173 (Fig. 8) fixed on the shaft 164:. The zero position of the total type wheels and total indicators is determined by the stop bar 174 with which the yoke 170 cooperates.

The cams 163, 173 and 138 are timed to operate in the order named to throw outthe aliners 161, to return the total type wheels and total indicators to zero, and to engage the gears 133 with the gears 115. When the gears are so engaged the totalizer is turned to zero and the total type wheels and total indicators adjusted by means of cams 180 (Fig. 3), secured to the shaft 167, a rocker 181 provided with rollers cooperating with said cams, and a link 182 connecting the rocker with asegment-gear lever 183 (Figs. 2 and 6) secured on a shaft 184 and in mesh with a partial gear 185 pinned to the shaft 124. Also pinned to the shaft 124 is a segment-gear 186 in mesh with a gear 187 which carries a spring-pressed pawl 188 cooperating with a ratchet 189 integral with a gear supported co-axially with and of the same size k as gear 187 and in mesh with a pinion 190 secured to a shaft connected to the turn-to-Zero shaft 101 by a universal short shaft portion 191 (Fig. 1) connected to the cam 109. This connection permits proper movement of the totalizer frame during item entering operations.

As the segment-gear lever 183 (Fig. 6) rocks first clockwise and then counterclockwise back to home position, it rocks the shaft 18 1 likewise and through arm 195 (Fig. 3) and link 196 moves a flash 197 from its home position to a horizontal position to cover the indicators as they are adjusted and then back to the position shown in Fig. 3. The flash is pivotally supported on shaft 145.

Each total-taking operation is registered on a consecutive numbering device which is operated by a lever 200 bifurcated at one end to receive a pin 201 on the link 182 and provided at its other end with a pin 202 (see also Fig. 9) cooperating with the bifurcation in an arm 203 mounted on a. stud 205' in the printer frame 73. The arm 203 is connected by a pin 206 with a yoke 207 actuating a differentially tined pawl to operate the consecutive numbering type wheels. The consecutive counter barrel also supports date type wheels 208 adjusted by sleeves 209 in a well known manner. The consecutive numbering device may be turned to zero by means of a knob 20 1.

Impressions are taken upon the issuing strip from the consecutive numbering and date wheels, the total type wheels and electros 210 and 211 to print a receipt as shown in Fig. 10 by an impression means 212 supported by an arm connected to a lever 213, one end of which cooperates with a box cam 211 fixed on the shaft 167, timed to operate after the total and consecutive numbering type wheels have been set.

Impressions from the total type Wheels may also be taken upon a detail strip 217 (Figs. 2 and 11) by a hammer 218 operated from the lever 213 by a link 219. Any suitable means may be provided to operate the receiving roll 220 for the detail strip during total taking operations.

After the impressions are made the issuing strip is fed out of the machine a suflicient distance to move the printed total amount beyond the knife edge. For the accomplishment of this function the shaft 83 of the feeding roller 82 carries a ratchet 225 (Fig. 3) operated by a pawl 226 carried by a plate 227 rigid with a gear 228 operated by a segment-gear 229. The segment-gear 229 is provided with a slot 230 which receives a roller 231 (Fig. 13) carried by a rocker 232 cooperating with cams 233 secured 0n the shaft 167. The cams are timed to feed the issuing strip after the impressions have been made.

The gears 133 are disengaged from the gears 115 after the totalizer elements have been turned to Zero and the total type and total indicator wheels adjusted. At this time the aliners 161 are moved back into alining position.

Operation.

The item amounts are indicated. accumlated and printed by operation of appropriate keys by mechanism all old in the art. The impression is taken upon a detail strip which is fed out of the machine as the items are registered. After all of the items involved in a transaction have been registered, the drive shaft 167 (Fig. 2) is actuated by a crank or any other suitable means. By mechanism previously described, operation of this shaft disengages the aliner 161 (Fig. 3) from the indicator alining segment, permitting the indicators and total type elements to be returned to home position by the bail or yoke 170 actuated by a pitman 172 operated from the cam shown in Fig. 8. The connecting gears 133 are then moved into mesh with the gears 115 (Fig. l) by a pitman (Fig. operated by the cam shown in Fig. 7. The rocker 181 (Fig. 3), which in the meantime had been rocked clockwise, is now moved counterclockwise, thereby actuating the pawl 188 by mechanism shown in Figs. 3 and 6 to rotate the turn-to-zero shaft 101 (Fig. 41). This rotates the totalizer elements to zero and through a train of gears shown in Fig. 3 moves the total type elements and indicators an amount proportionate to the amount on the totalizer, thereby setting up the total on the total type and indicator elements. The amount accumulated on the totalizer during the item registration now appears on the indicators and on the type" lines. The upper and lower impression member's" 2) are then operated as the rotation of the shaft 167 is continued, makin an imprint of the total on the detail strip and on the issuing receipt strip 85; Continued rotation of the shaft 167 causes the receipt strip to be fed to the left until the total impression has passed the severing edge 221. Viihen the machine is at rest, the portion of the strip fed out of the machine is torn'off and is handed to the customer as a receipt. This receipt bears information as shown in Fig. 10. 4
